Methods, systems, and devices for exchanging subband puncture information for network throughput management are described. In some examples, an access point may receive an action frame from a station device, which includes a disabled subchannel bitmap subfield that indicates subband puncturing information based on localized interference detected by the station device. The access point may then determine a negotiated subband puncturing pattern that considers both the station device's and the access point's detected subband puncturing information. Subsequently, the access point may transmit an action frame back to the station device containing this negotiated subband puncturing pattern. Both the access point and the station device may adhere to this negotiated subband puncturing pattern for future unicast frame exchanges, thereby enhancing network efficiency by effectively managing packet transmissions and reducing packet collisions.

Methods, systems, and devices for synchronizing Bluetooth access grants in Wi-Fi-connected devices are described. In some implementations, a method may include establishing a Wi-Fi connection between a first device and a second device, both equipped with Bluetooth capabilities. The method may involve determining a target beacon transmit time for the Wi-Fi connection and synchronizing Bluetooth access grants between the first and second devices based on the target beacon transmit time. Consequently, medium access may be granted to Bluetooth on both the first and second devices simultaneously in response to the synchronized Bluetooth access grants, thereby enhancing the efficiency of medium usage and improving overall device coexistence and performance in Wi-Fi/Bluetooth combination environments.

An access point (AP) may establish multiple virtual networks in a wireless local area network (WLAN) that are associated with a basic service set identifier (BSSID) of the AP and unique service set identifiers (SSIDs). The AP may transmit, to a station (STA) in the WLAN, a beacon including beacon data indicating the BSSID and at least one of an SSID that is not associated with the multiple virtual networks or an indicator that the AP is associated with one or more virtual networks. The STA may determine, based on the BSSID, to connect to a virtual network of the multiple virtual networks. The STA may transmit, to the AP, a request for discovery of the virtual network indicating a unique SSID of the virtual network. The STA may receive, from the AP and based on the request, a response confirming that the virtual network is available.

A station (STA) may connect to an access point (AP) via a plurality of wireless links. The STA may determine to transition a power management state of at least a first wireless link, of the plurality of wireless links, to a transitioned state. The STA may transmit, to the AP and over an available wireless link of the plurality of wireless links, a frame including protected data indicating the transitioned state of the first wireless link. The AP may transition the first wireless link to the transitioned state.

An access point (AP) point in a wireless local area network (WLAN) may include circuitry configured to transmit, to a station (STA) in the WLAN, a beacon including a beacon payload. A first set of information elements associated with the access point may be advertised within the beacon payload. The beacon payload may include an indicator indicating that the AP is associated with a second set of information elements that is not advertised in the beacon payload. The STA may include circuitry configured to transmit, to the AP, a request for the second set of information elements. The STA may receive, from the AP and in response to the request, a response including an indication of the second set of information elements.

A mixed-signal unit including a sampler circuit and a tracking filter. The sampler circuit converts a code into a reference signal. In response to comparing an input signal to the reference signal, the sampler circuit produces a bitstream. Upon receiving the bitstream from the sampler circuit, the tracking filter updates the code using information contained in the bitstream. The tracking filter outputs the code to the sampler circuit in response to the tracking filter updating the code.

The subject technology is directed to position sensing. In an embodiment, the subject technology provides a device for segment counting, which includes a top collector with first and second contacts, both associated with a first polarity. A first mount is connected to the top collector. A bottom collector, featuring a third contact with a second polarity distinct from the first, is positioned between and aligned with the first and second contacts along a defined direction. A second mount is attached to the bottom collector. A wire extends between the first and second mounts, oriented non-parallel to the defined direction. Additionally, the first and second deflectors are coupled to the bottom collector, with a portion of the wire positioned between them. There are other embodiments as well.

There is described a nanoporous composition, comprising: i) a first nanoporous component with a first pore characteristic; and ii) a second nanoporous component with a second pore characteristic; a) wherein the first nanoporous component and the second nanoporous component are mixed in the nanoporous composition; and b) wherein the first pore characteristic is different from the second pore characteristic, in particular thereby providing an adjusted hierarchical pore structure.

In some implementations, a device may include a transmitter associated with an access point (AP) corresponding to a basic service set (BSS) selectively operating in one of a first frequency range or a second range. The one or more processors may be configured to determine that the AP operates in the second frequency range. The one or more processors may be configured to determine that the transmitter has a limitation in transmitting using the second frequency range. The one or more processor may be configured to transmit, to the transmitter via the AP, a request to generate a frame including a recommended frequency range that is different from the first frequency range. The one or more processors may be configured to generate the frame including a recommended frequency range. The one or more processors may be configured to transmit, to the AP via the transmitter, the generated frame.

A traffic monitor is configured to alert a second vehicle about a first vehicle in front of the second vehicle, by performing the steps of: broadcasting a first request for speed information as a first Bluetooth Low Energy signal, the first request including a universally unique identifier associated with BLE, and then receiving a first response from the first vehicle in response to the first request, the first response containing data that indicates that the first vehicle is moving at a first speed; comparing the first speed to a threshold speed to determine that the first speed is less than the threshold speed, and determining, based on the first speed, a first time period for alerting other vehicles about the first vehicle; and alerting the second vehicle during the first time period about the first vehicle in response to the first speed being less than the threshold speed.
